rRAME FOR GOMBING MAcHmns.-

Application filed May 12,

and Republic France, have invented cern tam new and useful Improvements1n Frames for CombingMachines, of which the follow- 7 ing is a full,clear,and,exact description.

. This invention relates to combing machines of the Heilmann type andother types based on the same principle according to which the lapwhilst being held by a straight kind of combing devices such as amongstothers the inlet, the

feed apparatus, and thenipper, are mounted on the upper portion of aframe, the

lower portion of which comprises, amongst otherparts, the camshaft, thecircular comb,

the revolving brush and the doifer.

;.-It is likewise known that, as regardsthe circular comb which: iscomposed of one, two or more comb segments, the renewal of damaged rowsof needlesis attended by When the comb segment or segments are movedfrom the top, the nipper is still closed and is thereforee at itsminimum distance from the comb segment; this is an unfavourable positionand hinders the removal of the comb segments from the top.

It is therefore necessary to remove the comb segments from the back byrunning the machine backwards after having first removed the screws thatfix them on the comb stock discs or spiders, and also certain otherparts which would prevent the removing operation. This removingoperation is therefore a very delicate procedure necessitating skillfuland experienced handiwork whilst at the same timeentailing great loss oftime. These drawbacks are repeated when placing new segments intoposition, owing to the fact that it is desirable not I to damage the newrows of needles especially 1923; Serial 110,638,444. 7

placing the needle bars, especially those having closely spaced'needlesit has already been proposed to make the segment'in two portions.. Thatexpedient is however not perfect, because two comb segments fired onebehind the other on, the comb stock, never revolve inthe sameperfectlycircular inann er as a single segment, so that this constitutes afurtherdrawback in theworking ofthe combing machine.

ject to obviate the aforesaid drawbacks, and for th s purpose, itconsists in improve merits in the frames of combing machines of theHeilmann type and machines'based on this type, whereby'thecomb segmentsare rendered more accessible/and can be removed from the topwithoutidifficulty, with- .out requiring delicate handiwork, withoutthrowing the machineout, of. adjustment and without loss of. the,replacing of the new comb segments into position being attendedby thesalli advantages, in addition to-the important advantage of; being ableto use over agam the; combsegmenjts 'madein Thepresent invention has nowfor its ob one piece whichhas. been hitherto impossible inqthefmajorityof modern 1 combing machines I These improvements forming the subjectmatter of the present invention consist in principle in making the frameof the combing machines in two portions, namely a portion on which aremounted amongst other devices, the inlet, the feed apparatus and thenipper; this portionconstitutes the upper frame portion and is adaptedto rock on a pivot pin fixed to the other portion, namely the lowerframe portion which com prises amongst other devices a circular comb,

in such a manner as to enable the circular comb to be withdrawn, bymoving back the devices carried by the upper frame portion, and thusallowing of removing and replacing the comb segments easily and rapidlyand without throwing the machine out of adjustment.

In order to enable this invention to be more fully understood, aconstructional form thereof is hereinafter described and illustrated byway of example in the accompanying drawings in which Figure 1 is a sideelevation of a Heilmann combing machinefthe frame being shown closed,and themachine being in working position, and

Figure 2 is a similar View showing the frame opened to allow ofreplacing the comb segments.

From these figures it will be perceived that the improved frame iscomposed of two portions 1 and 2, the upper frame portion 2 beingadapted to be turned backwards by rocking on the pivot pin 3 fixed onthe lower frame portion 1, the extent of this backward movement beingsuch that it al lows the circular comb 4 to be completely disengagedfrom the nipper 5.

The upper portion 2 of the frame which latter is repeatedcorrespondingly on the other side of the combing machine, oonstituteswith its two cross pieces 6 and 7, a rigid framework carrying, amongstother devices, the inlet, the feed apparatus and the nipper. A rigidfastenin together of the two parts 1 and 2 is assured by any suitablefastening device, such as for instance, bolts 8 and nuts 9, the undoingof which allows the upper frame portion 2 to be rocked until a heelpiece or stop 10 comes against a shoulder 11 formed on or fixed to thelower frame portion 1.

In this position shown in Figure 2 the comb segments can be removed fromthe top and be replaced quickly and without difliculty, and withoutdisturbing the adjustment of the machine, owing to the fact that thelower cross piece 7, which carries the nipper springs and the springs ofthe feed apparatus, rocks with the whole combination around the pivotpin 3.

hen this operation is completed, the movable frame portion 2 is broughtback into its original position and fastened to the frame portion 1 bymeans of the bolts 8 I and nuts 9, or in any other manner,

It is to be understood that for the purpose of realizing theimprovements forming the subject matter of the present invention andapplying them to the various types of combing machine based on theHeilmann principle, the said improvements may undergo modifications,alterations in details,

and also that suitable mechanical equivalent may be used, withoutthereby departing from the nature of this invention.

What I claim is:

1. In a combing machine of the Heilmann type having an inlet, feedapparatus, a nipper and a circular comb formed in segments, a fixedframe on which the circular comb is journalled, a movable upper frame tocarry the inlet, the feed apparatus and the nipper, and a pivotalconnection between the fixed frame and the upper frame to enable thelatter to be swung to "withdraw the, nipper from the comb to permit easyand rapid replacement of the comb segments without throwing the machineout of adjustment.

2. In a combing machine of the Heilmann type having: an inlet, feedapparatus, a nipper and acircular comb formed in segments,

a fixed frame on which the circular comb is j ournalled, a movable upperframe to carry the inlet, the feed apparatus and the nipper, a pivotalconnection between the fixed frame and the upper frame to enable thelatter to be swung to withdraw the nipper from the comb to permit easyand rapid replacement of the comb segments without throwing the machineout ofadjustment, and means for securing'the movable frame firmly to thefixed frame when the machine is to be operated.

In witness whereof, I hereunto subscribe my signature.
